WILLIAM T.

CLAYCOMB, OF OWENSIBORO,

KENTUCKY.

To all whom it may concern:

Be it known that I, IVILLIAM T. CLAY- COMB, citizen of the UnitedStates, residing at Owensboro, in the county of Daviess and State ofKentucky, have invented certain new and useful Improvements in CombinedVentilator and Heating Apparatus, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to ventilators, and has special reference toventilating apparatus for reducing the temperature in an over-heatedroom.

The invention has for its object to provide a ventilating apparatus soconstructed and arranged as to be operated by the heat passing through astove pipe and thereby drawing the heat from a room in which said stovepipe is located.

The invention consists in a ventilating apparatus connected with a stovepipe and in details of construction thereof constructed and arranged ashereinafter set forth and claimed.

Referring to the accompanying drawings, Figure 1 is a view in elevationof a ventilating apparatus constructed in accordance with thisinvention, shown as connected with a stove pipe. Fig. 2 is a detailview, partly in section, of a portion of a stove pipe and a shaft fordriving the ventilating apparatus. Fig. 3 is a detail view in verticalsection of the lower end of the ventilating apparatus. Fig. at is a viewin elevation and vertical section of the apparatus shown in Fig. 1. Fig.5 is an enlarged detail view of a portion of the driving shaft of theventilating apparatus. Fig. 6 is a large detail View, partly in section,of a portion of the ventilating apparatus. Fig. 7 is a detail view invertical section of a portion of the stove pipe and its damper. Fig. 8is a detail View in vertical section showing the lower end of thecylinder 1 closed.

In carrying out this invention the ventilating apparatus consists of avertical cylinder 1 having at its upper end a detachable cover 2; andprojecting from one side of the cylinder and adjacent to its upper andlower end are lateral tubes or fiues 3 which are connected with and openinto a detachable section 4 of a vertical stove pipe 5. Mounted in thecylinder 1 and projecting through the cover 2 in its upper end is adriving shaft 6 formed in two sections 7 Specification of LettersPatent.

and 8 detachably connected together above the cover 2 by means of asuitable joint, as for example, a V shaped joint 9 which detachablyconnects the two sections of the shaft and is clamped by means of asleeve 10 and a set screw 11 bearing against the driving shaft. Thelower end of the shaft 6 is formed with a tapering point 12 which restsin a socket in a suitable support in the lower open end of the cylinder1, and as here shown preferably consisting of a cross bar 13 resting ona cross bar 14, the ends of said cross bars resting upon and beingsecured to L shaped brackets 16 depending from and secured to the lowerend of cylinder 1. The upper end of the shaft 6 rests in a socket 17 onthe end of a horizontal metal strip 18 secured at its inner end to adetachable clamp ring 19 having lips 20 connected together by a screw 21by means of which the ring 19 may be firmly clamped to the stove pipe 5.Mounted at intervals on the driving shaft 6 are a number of motorpropellers 22 which are slidably mounted thereon and are adjustable atdif ferent distances apart from each other by means of sleeves 23located on the shaft 6 on each side of each of said propellers andscrewed in place by means of a set-screw 24:, each sleeve 23 having aset screw 24 which binds against shaft 6. In the lower end of cylinder Imounted on the lower end of shaft 6 is a suction propeller 25 employedto draw air up into the cylinder 1 and on the shaft 6 adjacent to itsupper end is a fan 26 adapted by its movement to drive the air downward.

It will be seen that by means of the apparatus, as hereinbeforedescribed, the gaseous products of combustion ascending the stove i e 5will be carried through the lower lateral ne or tube 3 into the lowerend of the cylinder 1, a damper 28 in the flue pipe hav ing been closedto divert the ascending gases through the lower lateral flue or tube 3into the lower end of the cylinder 1. The passage of the gases into thelower end of the cylinder 1 acts upon the propellers 22 to rotate sameand therefore the driving shaft 6, the gases in their ascent passing outthrough the upper lateral flue or tube 3 and into and through the stovepipe 5. The shaft 6 being driven by the propellers 22 will cause the fan25 to be rotated and thereby suck the air from the room in which theapparatus is located up through the cylinder 1 and out into the stovepipe. The fan 26 also being driven by the shaft 6 will cause the hot airin the room in which the apparatus is located to be driven downwardthereby aid ing the fan 25 and causing the hot air in the room to bedrawn up into cylinder 1 and out of the same into the stove pipe.

If desired the grooved pulley 27 may be mounted on the upper part of theshaft 6 and connected by an endless belt with another shaft in the roomto drive another fan. By having shaft (3 formed in two sections theventilating apparatus may be removed from the stove pipe, theventilating apparatus being connected as described with section t of thestove pipe, which may be removed and the stove pipe section substitutedfor section 4.

It will be seen that by means of this invention a room may be thoroughlyventilated by having the hot air drawn out of the same and into thestove pipe in the room, the gaseous products of combustion passing upthrough the stove pipe serving to operate the ventilating apparatus.

When the ventilating apparatus is not desired for use, by leaving flue28 open in the stove pipe the gases will directly pass up and throughthe stove pipe without affecting the ventilating apparatus.

The foregoing described apparatus may also be used as a heater as wellas a ventilating apparatus, and for this purpose the lower end of thecylinder 1 is provided with a hinged door of any suitable construction,and, as here shown, in Figs. 1 and 8, consisting of a door 29 hinged toone side of the lower end of the cylinder 1 and adapted to be held inclosed position by any suitable means, as, for example, by means of thespring clips 30, which, when the door is closed, clasp the side of thecylinder 1.

When the door 29 is not closed it may be held out of the way by beingswung up against the side of the cylinder 1, and held there by anysuitable fastening.

When it is not desired to extract the heat from the room, the lower endof the cylinder 1 is closed by the door 29 thereby causing the cylinder1 to serve as a drum heater. In connection therewith, the heat at thetop of the room is thrown downward by means of the rotary fan 26 whichis operated by the heat passing through the cylinder 1 and acting on thefan mechanism in said cylinder. In this way the heat disseminated fromthe heater 1 is distributed about the room.

It will thus be seen that by means of this apparatus the heat may beeither drawn out of the room through the cylinder 1 or may be retainedin the room by closing the lower end of the cylinder 1. In this way theroom may be kept at an even temperature.

By this means the apparatus may be used in a cold as well as a hotclimate.
